In the Linux kernel, the following vulnerability has been resolved: vdpa_sim: fix possible memory leak in vdpasim_net_init() and vdpasim_blk_init() Inject fault while probing module, if device_register() fails in vdpasim_net_init() or vdpasim_blk_init(), but the refcount of kobject is not decreased to 0, the name allocated in dev_set_name() is leaked. Fix this by calling put_device(), so that name can be freed in callback function kobject_cleanup().
